That code unlocks the additional features of QuickTime Pro. Upgrading to QuickTime Pro does not require any additional software installation all you need is a registration code.
But even the brief list here should be enough to help you see that it is a worthwhile upgrade. In fact, QuickTime Pro's benefits are too numerous to list in detail. You can also use QuickTime Pro to save QuickTime movies you find on the Web to your Mac. For example, you can use QuickTime Pro to save QuickTime and other content in various formats for use in your projects. The Pro upgrade helps you in all digital lifestyle areas, not just QuickTime movies. With all the additional capability that it brings to your system, it is a very worthwhile investment.
Because you are serious about using a Mac (if you weren't, I assume you wouldn't have purchased this book), I suggest that you upgrade to QuickTime Pro. Before you start watching and editing movies, you need to do some configuration of QuickTime so you get the best results on your system.
